Phase I ESAs

Phase I environmental site assessments are completed in accordance with the most recent ASTM E1527 standard, including All Appropriate Inquiry. Site inspections are performed by professionals with a minimum of five years of experience in environmental field work, and reviewed by senior staff members. Reports include an Executive Summary written in non-technical language to simplify the review process by those who may not be familiar with environmental jargon.

Phase II ESAs

The scope of a Phase II Environmental Site Assessment is highly project-specific and will vary depending on the type of site being investigated, budget, regulatory requirements, and schedule. An effective Phase II investigation requires excellent communication between the client and the consultant to ensure that the client's goals are met in the most cost effective and expedient way possible.

Moonstone’s Phase II environmental site assessments are completed by experienced staff and reviewed by a licensed Professional Geologist. Phase II services may follow a Phase I assessment or may be a stand-alone service. Phase II services include, but are not limited to:

  • Soil sampling
  • Sediment sampling
  • Soil gas sampling (vapor intrusion)
  • Monitoring well installation
  • Groundwater sampling
  • Surface water sampling
  • Hydrologic/hydrogeologic evaluation
  • Contaminant transport analysis
  • Underground storage tank (UST) investigation

PADEP Act 2 Reports

Act 2 is the Pennsylvania Department of Environmental Protection’s (PADEP’s) voluntary cleanup program, also known as the Land Recycling Program. Act 2 uses risk-based health standards to establish concentration limits for regulated substances in soil and groundwater. If these concentration limits (known as the Statewide Health Standards) cannot be met, Act 2 provides an alternative, site-specific approach (known as the Site Specific Standard) that takes into account the specific exposure scenarios present at the site. There are also special provisions for background conditions and former industrial properties in economically challenged areas (Background Standard and Special Industrial Area, respectively). Act 2 is a very flexible, but complex, regulatory framework and requires an experienced consultant to successfully navigate the options.
